Abstract: Abstract of the Disclosure The method resides in mixing alumina-containing raw material comminuted in a soda solution to obtain a frac-tion of more than 0.08 mm in an amount of more than 12 per-cent by weight with carbonate raw material and a soda solu-tion in a weight ratio which ensures in the charge a mole-cular ratio of alkali metal oxide to alumina of at least 1 to 1 and a molecular ratio of calcium oxide to silica equal to 2?0.03 to 1, and simultaneously comminuting the solid compo-nents of the resultant charge to obtain a fraction of more than 0.08 mm in an amount of 2 to 15 percent by weight. There-after the resultant charge is corrected and sintered, the sin-ter is leached, the aluminate solution obtained is desilicated and aluminium hydroxide is separated by carbonating and de-composing the aluminate solution, and aluminium hydroxide obtained is calcined.           The method provides a 3 to 5 percent increase in the extraction of alumina and oxides of potassium and sodium from the sinter.  In addition, the proposed method makes it possible to reduce power consumption for the preparation of the charge by 20 to 30 percent; compressed air consumption is two to three times lower than in the method known in the art.

Abstract: ABSTRACT      The present invention relates generally to the manufacture of an asbestos free fibre reinforced carbonated building element by exposing, to the action of carbon dioxide, a shape formed from a slurry of cellulose fibres and a suitable oxide or hydroxide.          The invention deals particularly with the case in which the element is a sheet, the hydroxide is slaked lime, the fibres are from waste newspapers, the carbon dioxide is from waste flue gases, and the properties are those normally associated with asbestos cement sheets - in which case the invention produces, from lime and waste products a sheet that can at least replace asbestos cement sheets in all building applications.    The slurry is formed into the shape of the building element as a matted felt having a porosity before carbon-ation within the range 35 to 50%, interconnected pores the contain water, and a cellulose fibre amount in a preferred range of 7 to 40% by weight of solids.    The invention has three prime objectives:  the first is to achieve the properties of asbestos cement in the fibre carbonate building element.  The second is to achieve a higher rate of carbonation than in the prior art.   The third is to utilise waste material (e.g. flue gas and waste paper) thereby protecting the environment and preserving virgin resources.

Abstract: ABSTRACT OF THE DISCLOSURE An article clamp, particularly useful as an electrode clip, is pro-vided herein which is formed of resilient plastic material, e.g. polypropylene. The clamp includes an open bottomed box-like enclosure including opposed side walls, frontal and distal end connecting portions, e.g., as spaced apart front and rear partial top walls, and preferably also integral with opposed end walls and preferably also a pair of supporting flanges extending outwardly from an open bottom.  A primary electrical contact plate, e.g., of a channel-shape and having an access slot therein is disposed across a portion of the open bottom. The electrical contact plate has means to enable connection to an electrical lead wire, e.g., in the form of an upward extension thereof.  The clamp also in-cludes an articulable cover which is integral with the box-like enclosure.  The cover includes a first swingable member secured to a frontal connecting end of the box-like enclosure by means of a first living hinge. The first swingable member has a second cooperating electrical contact plate secured thereto.  A second swingable member is secured at one end thereof to the free end of the first swingable member by means of a second living hinge.  A third swingable member is secured at one end thereof to the free end of the second swingable member by a third living hinge, and to a distal wall of the box-like enclosure by a fourth living hinge.  An operating lever is integrally secured to the third swingable member.  In operation, when the primary electrical contact plate is disposed in electrical contact with the stud of the male electrode, and when the operating lever is urged downwardly toward the primary electrical contact plate, the first swingable member is urged downwardly to place the second co-operating electrical contact plate into electrical contact with the stud of the male electrode.  The third living hinge is moved to a positive over-toggle posi-tion to lock the contact plates and the male electrode stud in engagement with one another.  This electrode clip can be easily manipulated with one hand to secure the connector to the electrode stud, e.g. one temporarily attached to a human body, to a lead cable of an electrocardiograph, without any signifi-cant amount of pressure being applied directly downwardly to the stud and hence to the human body.

Abstract: 1                      PHB. 32,648.     ABSTRACT:                  An iterative real time histogram modification system for use in image processing, such as image contrast enhancement of for example scenes, radiograms and thermo-grams.  In the described system input analoque video sig-nals to be modified are digitized and applied to an encod ing module including a code RAM which compresses the input grey levels into a lesser number of output grey levels in accordance with a recoding strategy applied to the code RAM. The recoding strategy is determined iteratively using a pre-determined scene adaptive operator.  This is done by form-ing a histogram of the pixels in the respective output grey levels.  Thereafter the count in each grey level is compared with a predetermined population figure for that grey level and of the difference between the count and population figure is outside an acceptable range, termed a window, then the recoding strategy to be used during the next frame of the input signals is altered so that the number of input grey levels compressed into the particular output grey level is adjusted appropriately.  The recoding strategy may be applied to a local area of the frame, which area is selected at will, or to the entire frame in which case the histogram is formed from a subset of all the pixele.  The scene adaptive operators include histogram equalisation, Gaussian distribution, hyperbolic and exponential.  By using a suit-ably programmed microprocessor different scene adaptive operators may be selected at will and a "zoom" facility may be provided in which the size of the local area is varied and corresponding changes are made to the window and set of population figures.

IPC: E21B19/16
Filed: 1980-04-24
Granted: 1982-09-07
Abstract: Abstract of the Disclosure A chuck mechanism for a raise drill includes a rotatable drive shaft, drill pipe and chuck for engaging the drill pipe co-axial with the drive shaft and transmitting torque from the drive shaft to the drill pipe.  The drive shaft is rotatably coupled to the chuck with relative axial movement allowed.  First spaced apart cooperating contact surfaces between the drive shaft and the chuck can be brought together for trans-mitting axial force from the drive shaft to the chuck in the downward drilling direction.   Second spaced apart cooperating contact  surfaces between the drive shaft and chuck can be brought together for transmitting axial force from the drive shaft to the chuck in the upward raise drilling direction.  The drive shaft and chuck move axially relative to each other when contact is switched from the first to second contact surfaces or vice-versa.  The second pair of contact surfaces are shaped and dimensioned for allowing relative angular movement there-between when the drill pipe is deflected laterally.  An outer support is connected to a non-rotatable portion of the raise drill in the path of movement of the chuck for absorbing any moment load exerted by the drill pipe when it is angularly deflected.

Abstract: ABSTRACT          A telephone system with central processor control has telephones including respective data circuits. Each data circuit scans a respective keypad and stored data relating to the state of the keys thereon.  The stored data is forwarded to the central processor on demand from the processor.  The data circuit scans the keys of the keypad and then scans a data input connected to the central processor.  On detection of a prefix pulse from the central processor the data circuit makes repeated samples of this data input until detection of a start pulse.  Once the start pulse has been detected the data circuit scans the data input at the bit rate. If a key of the keypad changes state more than once between each demand from the processor, the respective data relating to the subsequent change is not modified by the data circuit.

Abstract: ABSTRACT OF THE DISCLOSURE       A long fishing line method and apparatus are respectively centered on the use of movable multiple skate racks, which upon hauling, receive a string of gear or interconnected skates, with the fish just removed, via a two position, vertical and horizontal, main hauler operated in conjunction with a slack taker, and which upon setting, distribute a string of gear or interconnected skates into a water agitated and stirred automatic fish hook baiter.  Each movable skate rack preferably holds substantially 1800 feet of ground line with approximately 600 hooks with their gangions of 10 to 25 inches long, spaced at 30 to 48 inches.  The fish hooks of each skate are conveniently and firmly held in a vertically captive position with their pointed ends placed over and then rotated down within a top opening integral receiver, extending a full length of the movable skate rack, which also has an integral upright full length planar bar, with near end cutouts used in slidably mounting the movable skate rack alongside others on hanger beams.  Upon hauling in a buoyline, the main hauler rotative drive shaft is horizontal, thereby positioning the sheave vertically, and there-after upon hauling in the ground line of the long fishing line, with its gangions and fish hooks the main hauler rotative drive shaft is vertical, thereby positioning the sheave horizontally.  When setting the long fishing line, with a boat underway, a buoy is throw over-board and a buoyline follows under the created pulling force.  Then an anchor enters the sea carrying the lower end of the buoyline and the start of the ground line toward the bottom, as interconnected skates are pulled from successive movable skate racks, and each hook is guided through a water stirred baiter to snag bait, a follow on bait recovery channel, and then into the sea.
